Polls released Sunday morning show real estate mogul Donald Trump holding his leads in the early voting states of Iowa and New Hampshire, although those leads are smaller than one more ago.
Trump leads Carly Fiorina among potential NH GOP primary voters by just 5 points, 21 to 16 percent, according to NBC News/WSJ/Marist pollsters.
Trump and Fiorina are trailed by former Florida Gov. Jeb Bush with 11 percent and Sen. Marco Rubio and retired pediatric neurosurgeon Ben Carson with 10 percent apiece.
In September, Trump led Ohio Gov. John Kasich, his closest competitor at the time in New Hampshire, by 16 points, 28 to 12 percent.
In Iowa, Trump now leads Carson by 5 points, 24 to 19 percent. Fiorina follows with 8 percent, Bush with 7 percent and Sen. Ted Cruz (Texas), Rubio and Louisiana Gov. Bobby Jindal with 6 percent each.
One month ago, Trump led Carson by 7 points in the Hawkeye State, 29 to 22 percent.
